They may have been allergic to the grains etc. in NutriLife All Gold (Brown Rice, Pearled Barley, Oat Meal, White Rice, Brewers Dried Yeast, Alfalfa Meal).

Possibly so, though more likely than if they were from the same litter, they are from two completely different breeders and lines and 2 weeks apart in age, one is short coated and the other is long coated.
I’m not sure how I feel about the brown rice, I know I’ve read that rice in general is often contaminated with trace amounts of arsenic, and that brown rice has a higher level than white.
This might offer some insight into this issue:

“How much arsenic is in your rice?
Consumer Reports’ new data and guidelines are important for everyone but especially for gluten avoiders
Published: November 2014
We looked at data released by the Food and Drug Administration in 2013 on the inorganic arsenic content of 656 processed rice-containing products. We found that rice cereal and rice pasta can have much more inorganic arsenic—a carcinogen—than our 2012 data showed. According to the results of our new tests, one serving of either could put kids over the maximum amount of rice we recommend they should have in a week. Rice cakes supply close to a child’s weekly limit in one serving. Rice drinks can also be high in arsenic, and children younger than 5 shouldn’t drink them instead of milk.
Brown rice has 80 percent more inorganic arsenic on average than white rice of the same type. Arsenic accumulates in the grain’s outer layers, which are removed to make white rice.”

Wellness CORE Grain-Free Puppy Formula is a great choice. Orijen Puppy Large Breed Grain-Free Dry Dog Food is outstanding. But as I said, it’s all trial and error until A) you like what you’re buying & B) you see outstanding stools & weight formation that’s appropriate.

I saw the Orijen, but the price was out of my range, if I was feeding a Beagle or small dog it wouldn’t be bad, but the $79 price and the even smaller bag yet than I normally buy that’s a double hit- higher price for less in the bag.

If you’re not already, spread out the meals as evenly as you can during waking hours, small portions equal to the daily amount (or what they’ll consume) 3 to 4 times per day. It’s easier on their tummies.

Jiggs came when he was 6-1/2 weeks old, I fed him 4 times a day until he was 8 weeks and then Hachi came shortly after and he was 8 weeks, and by then both are on 3 feedings a day
